FELT-BOOT MACHINE.

5PECIEICATION forming part of Letters Patent No. 323,457, dated August2,1885.

Application filed February 4, 1885. (No model.)

.To all whom it may concern.-

Be it known that I, WILLIAM A. SMITH, of Lawrence, in the county ofEssex and State of Massachusetts, a citizen of the United States, haveinvented certain new and useful Improvements in Felt-Boot Machines, ofwhich the following is a specification.

My invention relates to machines in which a sliver of wool or feltingmaterial is formed into a hat to be subsequently manufactured into afelt boot, shoe, or stocking; and it consists in improvements in themechanism whereby this operation of forming the bat is carried out.

In the drawings, Figure 1 is a top plan view, and Fig. 2 a front view inelevation, ofa ma chine embodying my present improvements. 3 is avertical end view of the same; and Fig. 4: is a plan view of a portionof the apparatus,to be hereinafter more specifically described.

In machines of this class there are commonly employed a pair ofrcvoluble rollers, each be ing in contour as if composed of a pair oftruncated cones, as shown at A A, upon which there rests and revolves adouble cone or former, 13. To these rollers and the cone which restsupon them there is given a radial motion derived from the radial motionof a table, C,

with which they are in connection, and also a lateral or reciprocatingmotion. Furthermore,

these rollers are revolved by means of suitable gearing connecting themwith the main source of power. My present improvement relates 35particularly to improvements in the devices whereby these movements areobtained.

The table 0, I prefer to make segmental in form. It has a center ofmotion at or near the inner apex of the segment, and. it is caused to 0oscillate or swing around this center in alternate directions by meansof a connecting-rod, D, operating by a rotating disk, E, which ismounted upon a shaft connected by beveled gears and shafting with themain source of 5 power X. To obtain thelateral motion of the rollers AA, I mount each upon a shaft, F, journaled in a supporting bracket orstandard, G, attached to the table 0, the rollers being splined to theirshafts and the shafts being made enough longer than the rollers to allowthem to slide thereon a distance equal to the lateral motion required.To produce thislatoral or sliding motion of the rollers upon theirshafts, I provide a slide or bracket, H, of which a plan view is givenat Fig. 4. Lateral 5 motion is given to this slider by means of a studcarried upon a rotating disk, I, and adapted to travel crosswise of theslider in a slot, K, formed therein. Rotary motion is given to this diskI by a beveled gear, L, connected with the disk and meshing with asimilar gear,

M, upon a shaft, N, which in turn is connected by beveled gears with theshaft driven by the main source of power.

The rotary motion of the rollers A A, which rotate in the samedirection, is obtained by gears O O at the ends of the shafts F F, thesegears being connected by intermediate gearing with a gear, 1, upon ashaft, 1?, which also carries a beveled gear, P which meshes with thegear M on the shaft N, before described.

By my present invention, as will be seen, I have simplified themachinery heretofore used in this class of work, and by the constructionand arrangement of the sliding rollers and their operating mechanism Iobtain a continuous to-and-fro movement of the rollers without theemployment of any reversing device or any special or additionalmechanism for changing the direction of their movement.

I also obtain by my present invention an important advantage overmachinery heretofore used, of which the Letters Patent No. 293,7 66contains an example, wherein the toand-fro motion of the rollers isobtained by reciprocating not only them, but also their axles, thestandards which carry them, and all the parts required to drive them. Insuch machines, as will be seen, considerable power 0 is required-toovercome the inertia and momentum of all these parts. By my presentinvention, however, I move practically nothing except the rollers orformers themselves, and thus I am enabled to do away with the neces- 5sity of moving a number of heavy parts, and the efficiency of themachine is thereby materially increased.

I claim 1. In a felt-boot-for1ning machine, the roll- I00 ers A A insplined or sliding connection with their revoluble shafts F F, saidshafts being splinedthereon, the slotted slider H, disk and pin I, andsuitable gearing and shafting, substantially such as herein described,whereby rotary motion is transmitted to the disk I, substantially as setforth.

In testimony whereof I have hereunto subscribed my name this 30th day ofJanuary, A. 20 D. 1885.
